I took some tiles from each tileset and compared them. Indeed, you can see
that whoever made the GX tileset definatly took some of Era's tiles, and or,
modified.

Pretty much each comparison is obvious, but the last one, take a close look,
it's the same gfx style! The person who made GX's tileset is different than the
person that made Era's tileset, and I'm sure they both don't have the same
style.

Keep in mind GX is left and Era is right.

Oh, and the obvious one is the rounded sidewalks which originated in Era.
